無法從 Ubuntu 上的 Gmail 通過 Python 發送電子郵件

Question

我在 Ubuntu 20 上運行 DigitalOcean 服務器並嘗試發送通知電子郵件。 該代碼在我通過瀏覽器手動登錄到 gmail 帳戶的 Windows 上運行良好。 但是在 Ubuntu 上，我收到 534 身份驗證錯誤。 問題是 Google 不支持非 JavaScript 瀏覽器，因此我無法通過任何命令行登錄，例如 Lynx 或 Links/Links2。

您應該啟用“不太安全的應用程序”訪問（找不到文檔鏈接，谷歌計划最終關閉此功能AFAIR）或使用“應用程序特定密碼”（ https://support.google.com/accounts/answer /185833 )
